Description

This image depicts Jupiter as it appeared early in the morning on 17 August 2023. During this session, seeing conditions were excellent, transparency was above average, and the Jupiter high above the horizon -- all in all, this made for very good conditions for imaging.

I have oriented the south pole upward in this image, with the Great Red Spot receding from view to the left. The image was obtained using my C11 telescope, compiled from a sequence of 12 videos taken from 4:25 am - 4:53 am PDT, each roughly 90 s in duration (for ~4200 frames per sequence and 50,000 frames total). Jupiter ranged between 56 - 61 degrees above the horizon during this sequence of videos. The data was acquired at 50 fps, with a gain of 345, and exposure time of 18.6 ms per frame. For this image, I stacked the best 25% of the total frames captured and used WinJuPos to perform derotation.

Again, I am very impressed with the improvement in resolution possible with the C11 compared with the C8 -- the increased level of detail that I was able to resolve is much more than I anticipated. The IMX 585 sensor is also very impressive for its low noise -- a few test images I had obtained on a couple of nights earlier (where clouds limited the number of captures) still showed very good detail.
